When is a popular Source such as a new article more appropriate?

In your research project or paper, you need to show how your ideas relate to those of others. In most cases, you'll want to use articles from scholarly journals to support your arguments because these are written by experts, include references you can consult, and have been carefully edited. Sometimes, depending on your topic, you'll need to use articles from popular magazines. Be sure to check with your professor or instructor that the sources you're using are acceptable for the assignment's requirements. Finally, whatever sources you use, evaluate them carefully. Does the author show bias and does it affect his/her conclusions? Is the information accurate? Does the author support his/her arguments with credible evidence?
